She's still got it

Speaking to E! News, she said: "I like women to feel very confident in how they look and to accept that every size can be beautiful.

"But I still think it's important to be in shape.

“It doesn't matter really what size you are, but I think it's important to stay sort of firm and to do a reasonable amount of walking and exercise.

I don't go to the gym, but I'm quite active."

She continued: "I hike, I walk with my dogs all the time and I don't really sit still.

"I don't really lie around on the sofa much. I like running around, so I don't feel like I need to be skinny, but I feel the need to be athletic and fit. That to me is the most important thing for people to do."

The Royals star also says she makes it a rule to avoid late-night meals: "I think that's one of the best diet tips you can have to eat your food earlier on in the day, so you've got more time to digest it and your body can rest in the sleep period.

She also knows how to work a one piece

"I think that's quite important. I always used to snack late at night because I was a little bit hungry before I went to bed.

“I stopped doing that now. But I think whole grains and vegetables and fish and small bits of lean meat is really the way I tend to go."
